Bind DataSet in Snap Report API

Hi,

I researched the template document you provided and found that all the Snap Lists in this document have the SnapList.DataSourceName property set to an empty string.

When you create a template document and drag a field from the Data Explorer, SnapControl inserts a SnapList instance in accordance with the selected DataSource in the Data Explorer. Each field dragged from the selected DataSource is inserted inside a corresponding SnapList instance.
So, each snap field is mapped to the corresponding field in the data source by the field name and SnapList's data source name.

Since the SnapLists in your template don't have a data source name, it is impossible to obtain the corresponding data field and retrieve data in your scenario.

To overcome the issue, it is necessary to redesign the template document. Create a document data source for each DataTable in the Dataset. Add SnapLists with the required snap fields and save the template.
To export this report to PDF, assign the data sources with the same names to the SnapDocumentServer component.

I recommend you check our Snap Demo - Multiple Data Sources demo to get started.
